When to Use JPG Quality 80%
Use quality 80% for all web images, social media, email attachments, and any image that will be viewed on screen. The visual difference from Q100 is imperceptible to the human eye in normal viewing conditions, while file sizes are 60-70% smaller.
When to Use JPG Quality 100%
Use quality 100% only for archival storage, master files that will undergo further editing, and print-ready deliverables where maximum quality is required. For web delivery, Q100 wastes bandwidth without visible benefit.
